目的：探讨舌癌术后部分缺损重建修复后语音频谱变化情况。方法以39例舌体切除范围不超过中线的舌癌患者和42例正常对照组患者为研究对象，采用语音分析软件对2组研究对象发元音／a／、／i／、／u／时共振峰进行比较分析。结果与正常对照组相比，舌癌术后患者发／i／、／u／时 F1上升、F3下降，发／i／时 F2下降，／u／F2上升。结论舌癌术后患者元音频谱发生变化，使用 VS-99语音工作站可对舌癌术后患者语音功能恢复进行定量分析评估，为临床舌癌术后部分舌缺损重建语音功能训练提供参考。

Objective To investigate the changes in acoustic characteristics of vowels after re-construction of partial glossectomy defects in patients with tongue cancer.Methods The formant frequencies of vowels/a/,/i/ and/u/ were analyzed by using VS-99 phonetics workstation in 39 tongue cancer patients who underwent glossectomy within the range of hemi-tongue and 42 nor-mal controls.Results Compared to normal controls,F1 values of/i/and/u/and F2 values of/u/increased,but F3 values of/i/ and /u/ and F2 values of/i/ decreased in patient who underwent glossectomy for tongue cancer.Conclusion The acoustic characteristics of vowels were changed after glossectomy.The VS-99 phonetics workstation can quantitatively assess postoperative recov-ery of phonetic function and provide a reference for phonetic function training after the recon-struction of partial glossectomy defects in patients with tongue cancer.
